I have AS, my wife has OCD, the cousin I grew up with has diabetes - as Gilda Radner wisely used to say:
"It's alllways somethin'; if it's not one thing, it's another. Goodnight my lil' Roseanne Rosannadanna."
For her it was cancer. I'll keep my AS, thanks.
I know it's not much consolation when you're feeling blue, but everybody has challenges, whether they care to admit it or not. You are in the fortunate position that in the more civilized nations your challenge is legally recognized as a disability, thereby making you eligible for many types of assistance you might not otherwise have access to.
Still in all, I know there are those moments when you know where you want to go and what you need to do, and you feel that magnetic force field that keeps you from moving forward, in spite of your most willful efforts. Hang in there, this, too, shall pass. Until the next time it happens.
